Some Thunderbird help?

[Jorlem]

Could someone with more experience working with Mozilla Thunderbird give me a hand?  I can't send messages out through my Gmail account using Thunderbird.  Stuff gets downloaded into my inbox just fine, but when I try to send something I get this error message:

Send Message Error

---

Sending of message failed.
An Error occured sending mail: Unable to connect to SMTP server smtp.gmail.com via STARTTLS since it doesn't offer STARTTLS in EHLO response. Please verify that your Mail/News account settings are correct and try again.

Its been like this for a few weeks now, but I've gotten fed up with poking at it and trying to fix it myself.  I hadn't changed any of the settings from when it worked before, it just didn't work one day when I tried to send an email.  As far as I can tell, all of the settings are configured properly, as according to the online help thing for setting up Thunderbird 2 with Gmail.

It's seems like Thunderbird installation might have corrupted itself somehow. You could always try reinstalling the application.

If I do that, will I loose the stuff that's saved in my inbox, and my address book and everything?

I think you can export them. I'm not sure how tbh. I normally use the Opera client.

Edit to add: most popular answer suggest that outbound mail scanning by your virus scanner is the culprit.

Awesome! That did it. Thanks a ton. Don't know how I missed that help article myself. Thanks.
